Mind-wandering as spontaneous thought: a dynamic framework
Kalina Christoff,Zachary C. Irving,Kieran C. R. Fox,R. Nathan Spreng,Jessica R. Andrews-Hanna +4 more
TL;DR: It is proposed that mind-wandering is best understood as a member of a family of spontaneous-thought phenomena that also includes creative thought and dreaming, and can shed new light on mental disorders that are marked by alterations in spontaneous thought, including depression, anxiety and attention deficit hyperactivity disorder.

Controllability of structural brain networks.

TL;DR: Tools from control and network theories are used to offer a mechanistic explanation for how the brain moves between cognitive states drawn from the network organization of white matter microstructure and suggest that densely connected areas facilitate the movement of the brain to many easily reachable states.

The cognitive map in humans: spatial navigation and beyond
TL;DR: Recent studies indicate that the human hippocampus and entorhinal cortex support map-like spatial codes, and posterior brain regions such as parahippocampal and retrosplenial cortices provide critical inputs that allow cognitive maps to be anchored to fixed environmental landmarks.

Prospective representation of navigational goals in the human hippocampus
Thackery I. Brown,Valerie A. Carr,Valerie A. Carr,Karen F. LaRocque,Serra E. Favila,Alan M. Gordon,Ben Bowles,Jeremy N. Bailenson,Anthony D. Wagner +8 more
TL;DR: Testing whether the human hippocampus and interrelated cortical structures support prospective representation of navigational goals demonstrated that hippocampal activity patterns code for future goals to which participants subsequently navigate, as well as for intervening locations along the route, consistent with trajectory-specific simulation.

Finding the self by losing the self: Neural correlates of ego‐dissolution under psilocybin
Alexander V. Lebedev,Alexander V. Lebedev,Martin Lövdén,Gidon Rosenthal,Amanda Feilding,David J. Nutt,Robin L. Carhart-Harris +6 more
TL;DR: The results implicate MTL‐cortical decoupling, decreased salience network integrity, and reduced inter‐hemispheric communication in psilocybin‐induced ego disturbance and suggest that the maintenance of “self”or “ego,” as a perceptual phenomenon, may rest on the normal functioning of these systems.

The Fusiform Face Area: A Module in Human Extrastriate Cortex Specialized for Face Perception
TL;DR: The data allow us to reject alternative accounts of the function of the fusiform face area (area “FF”) that appeal to visual attention, subordinate-level classification, or general processing of any animate or human forms, demonstrating that this region is selectively involved in the perception of faces.
Journal ArticleDOI
Separate visual pathways for perception and action.
TL;DR: It is proposed that the ventral stream of projections from the striate cortex to the inferotemporal cortex plays the major role in the perceptual identification of objects, while the dorsal stream projecting from the stripping to the posterior parietal region mediates the required sensorimotor transformations for visually guided actions directed at such objects.

Rhythms of the brain
TL;DR: The brain's default state: self-organized oscillations in rest and sleep, and perturbation of the default patterns by experience.
Journal ArticleDOI
Dynamic predictions: Oscillations and synchrony in top–down processing
TL;DR: It is argued that coherence among subthreshold membrane potential fluctuations could be exploited to express selective functional relationships during states of expectancy or attention, and these dynamic patterns could allow the grouping and selection of distributed neuronal responses for further processing.
Journal ArticleDOI
A cortical representation of the local visual environment
TL;DR: Evidence is presented that a particular area within human parahippocampal cortex is involved in a critical component of navigation: perceiving the local visual environment, and it is proposed that the PPA represents places by encoding the geometry of the local environment.
